Guidelines for Using the Privacy Mechanism for SIP
Abstract
This is an informational document that provides guidelines for using
the privacy mechanism for the Session Initiation Protocol (SIP) that
is specified in RFC 3323 and subsequently extended in RFCs 3325 and
4244. It is intended to clarify the handling of the target SIP
headers/parameters and the Session Description Protocol (SDP)
parameters for each of the privacy header values (priv-values).
